UNITED STATES PATENT OFFIGE.

FREDERIO H. L. o. SAOO, OF NEUFOHATEL, SWITZERLAND.

IMPROVEMENT I N PROCESSES OF PRESERVING BUITER.

Specification forming part of Letters Patent No. 171,532, dated December 28, 1875; application filed I November 4, 1875.

To all whom it may concern:

alcohol. The butter thus prepared is put in,

suitable receptacles, such as earthen, glass, metal, or wooden vessels.

When'it is desired to use the butter it is washed by kneading in fresh water, after which it will be found as fresh and pure as though newly made.

By the process above described the butter may be preserved for an indefinite length of time. I have thus lgept butter for two years or more absolutely intact and pure.

I can make use of all alcohols, either pure or mixed with coloring or aromatic matters.

I do not claim, broadly, the use ofalcohol as a preservative for butter; but

I claim The described process of preserving butter by mixing the same with two per cent. of alcohol at 90 0., as set forth.

In testimony whereof I have hereunto signed my name this 3d day of November, A. D. 187 5.

FREDERIO SAGO.
